I thought I had a grasp of this basic stuff, but apparently not.
I want to put a 315w 10A panel on my van (12v system). I'd planned on putting this in as the Charge Controller:
***
Epever solar charge controller 20A XTRA2210N
Tracer 2210AN MPPT Charge Controller
12V / 24V DC Auto
Max Input Power:12V @ 520W | 24V @ 1040W
Max.PV open circuit voltage:100VDC (92V at 25 temperature)
Battery type: lead-acid (Gel, Sealed, Flooded) and Lithium
Battery voltage range: 9V~32V C
***
However, I've been told the the maximum power that I'll be able to get, from the panels, through this device is 120w - 'we recommend you get the 30A version'.
What am I missing here? I thought I had the basic specs covered...
